About These Birds
Papuan Mountain-pigeon
山裸眼鸽分布于新几内亚的山地森林。体羽深灰，眼周裸露皮肤呈红色，胸部棕红色。栖息于海拔较高的山地雨林，以果实为食，尤喜无花果。成小群活动，常在树冠层觅食。因栖息地保存较好，种群数量相对稳定。
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
